88 mx6 gt starts when it wants. Help?
Okay, lemme apologize beforehand for being an idiot when it comes to cars. Any cars. I think all cars look the same. Car shaped.
That being said, my friend/roommate can look at any care on the road and tell you the make model an year. He, however, does not like going online to ask for help, so if I don't do it, we'll never get this solved, so I am doing this on his behalf. Mostly. Just so you know that everything I say has been from what he's said, and he doesn't know I'm coming here.
I AM coming here because for all our problems, this site has been tremendous amounts of help, but I feel it's time I sought out specific problems to this car and see if I can them answered. Any and all help would be appreciated.
So, first of all, a little history of the car. He bought an 88 mx6 from this idio- I mean friend. No scratch that. He's an idiot. I know nothing about cars, but I know to "cool down an egine faster" you don't "Poor ice cold water on it." But idiot had bought the car from someone else. Someone who took off the power steering belt because 'it keeps the car straighter' and sawed off the exhaust at the catalytic converter to increase horsepower.
And he had paid about a $2000 for it I think, and was doing things like running it hot and pouring cold water on, or without oil.
Now, my friend is the guy people usually ask to help fix their car, and 9 times outta 10, he can fix it himself. When the idiot friend couldn't get his car started, he called my roomate, who showed up, took about 5 minutes for him to look and undo the fuel filter and tap out a bunch of brown sludge and tell him he needs a new one. Not that idiot listened. We'll call idiot "Nef" and my friend "Jay".
Now, Nef always only used water in his radiator. Period. And one day he calls saying his car overheated, died, and needed towed because he couldn't get it to start again. Jay couldn't fix it without paying parts for it, and Nef couldn't afford parts so he was going to junk yard it for scrap for quick cash. So Jay paid him $200 instead to take it off his hands. it was agreed, and the thing is in the parking lot of our complex.
Now, when Jay looks at an engine and goes "WTF" something is wrong. Usually he can ghetto fix it to work, but alas, not this time. For one, it's a brand new fuel filter, but the care actually will turn over if it's NOT HOOKED UP. It'll run for a little bit, but obviously it shoots gas everywhere. He checked the lines, nothing's cracked, no leaks, nothing. The car still started and would run, but it would run hot, just idling, and the idle was low and it would shut back off if you didn't hold down the gas. When he took off the hose to the intake while messing with the idle, it was leaking some green-brown soupy stuff. I took all the hoses off, even the filter and the ones that go to the intercooler, and they were filled with the stuff. When I got to the turbo it was practically pouring out of it. So we took off the turbo, all those hoses, cleaned them out, used throttle cleaner to clean the stuff out of the intake. Put it all back. Still nothing, obviously, but the car wasn't making a funny smell it was before which we guessed was that wierd smelling stuff trying to burn?
So we checked for spark, and there was none. Well, first of all, the firing order was wrong I guess, which explains why it would randomly start and take a few tries. From what we looked up on line it's "1342" going clockwise from the cap.
Another thing, we took off the distributor cap and rotor, which had worn down from a plate to a blade, so I bought a new rotor, cap, and plug wires. He bought some E3 spark plugs as well.
So, we tried again, and hey! the car starts without overheating as quickly as before, but it has this knocking he says sounds like 2 cylinders arn't firing, and the idle won't stay. Then it wouldn't start again. It takes trying over and over and gently nudging the gas and then praying. So, we moved on to timing. We had bought one of the books, but the book was for the 323,626,probe,mx6 and the rx7. One of the instructions on how to take apart somethine was "unbolt it and remove" So it was just about useless.
We eventually figured it out in the book, or at least I assume we did. We got the top gear (Cam shaft?) to have 1 pointing up, and the bottom one has the white dot facing up. If theres more to that, please help there too. Jay will admit when it comes to getting THAT technical with an engine he's at a loss. This is like a project car I suppose to try an learn.
Anyways, that helped get it started without him cranking so much. Most of the time we've got the battery hooked up to his car because it keeps dying so quick.
But again it would start, but the idle wouldn't stay, and if you turned the car off, it wouldn't start again, and the timing would be off. We never put any of the exhaust back on since we figured we'd be messing with it all again. You could actually hear the turbo 'psssh' though, which you couldn't when Nef had it.
I don't know how this led to the head gasket, but I guess someone told him that's the knocking, and it's blown. SO we took the head off, opened, it was full of that wierd sludge we've come to assume is a mixture of oil and radiator fluid (That he had put in the radiator after we cleaned the turbo and hoses out.) And the head was aaaallll kinds of melted and cracked looking. So, he replaced that, and we found on this site how to torque it back down properly. If theres something we might have done wrong, please let us know. We torqued it to 64 pounds I beleive.
Also, we bought pipe parts and made a a new exaust. Put the whole thing back together and gave it an oil change. AAaaand we're back to square one. Now theres a whole new noise coming from the cylinders when we try to start it, a whole new smell, and it won't start again.
Ask me anything, or tell me what we're missing, but we NEED a second car. We've only spent like, 4-500 on this car, so getting it up and running would be better than payin 1-2000 to get another whole car and having to fix whatever might be wrong with it.
Car was ran hot, constantly,
fuel filter was usually clogged, wasn't replaced till MUCH later, and would try to start better if disconnected.
the spark plugs, distributer cap and rotar, and wires have been replaced.
The head gasket has been replaced.
turbo and air hoses have been cleaned out and haven't been filled with that stuff since.
the battery has been charged prior to use, or jump started with another car.
the previous two owners were very stupid and who knows what else could be wrong.
There is also an on/off switch right behind the fuel pump up against the firewall that we have no idea what it does or where it leads to, but we're pretty sure it does nothing, and don't know if that's factory?
Ask me anything, elaborate on anything we might have done wrong, just pleeeeaaaase help us!
